Home loans in Spring, TX work differently than in most Houston suburbs because the Spring area straddles two counties, Harris and Montgomery, each with its own tax structure and appraisal district. The 2026 conforming loan limit is $832,750 in both counties, so program eligibility does not change by county, but property taxes, MUD levies, and down payment assistance rules do. Confirming the county for a specific address before going under contract avoids the most common Spring mortgage surprise.

If you are weighing home loans in Spring, TX and trying to make sense of Springwoods Village near the ExxonMobil campus, the historic charm of Old Town Spring, the Klein and Spring school district boundaries, or how the Harris and Montgomery county line affects your tax bill, you are in the right place. Spring is one of north Houston’s most active purchase corridors, anchored by the I-45 and Grand Parkway interchange, and the mortgage process here carries a few wrinkles that catch buyers off guard if no one walks them through it first.

Why Do Home Loans in Spring, TX Cross Two Counties?

Spring is one of the few north Houston markets where the county line runs straight through the community. The southern and eastern sections sit in Harris County, while the northern sections near the ExxonMobil campus and the Springwoods Village area extend into Montgomery County. Most buyers do not know which county a particular subdivision falls in until they pull the tax record or ask a lender to read the legal description.

Here is why the county matters when you are comparing home loans in Spring, TX:

• Conforming loan limit: For 2026, the conforming limit is $832,750 in both Harris and Montgomery counties. Because the two counties share the same limit, loan program eligibility does not shift by county. The FHA limit is $541,287 in both counties as well. What does change between counties is the tax math, so confirm the applicable limit by property address before assuming FHA eligibility on a higher-priced Spring home.
• Property tax structure: Harris County and Montgomery County set different rates and use different appraisal districts. On a $360,000 Spring home, a 0.3% difference in the effective rate works out to roughly $1,080 per year, or about $90 per month on your escrow payment. That is a meaningful number to pin down before pre-approval, not after.
• Down payment assistance: Some assistance programs are tied to the county where the property sits. Harris County HFC programs apply to the Harris County portion of Spring, while Montgomery County addresses follow Montgomery County and statewide rules. Matching your assistance program to the right county is part of getting the numbers right.

Which Loan Programs Fit Home Buyers in Spring, TX?

Spring’s purchase market runs across a wide price band, from established homes in the $250,000s near FM 1960 and Old Town Spring up through newer construction above $500,000 in Springwoods Village and the master-planned communities along the Grand Parkway. That range means different programs fit different buyers. Here is how the main options line up for home loans in Spring, TX.

All loan programs subject to credit approval, underwriting, and current program availability. Loan limits and program guidelines are subject to change. Fairway Independent Mortgage Corporation, NMLS #2289. Equal Housing Opportunity.

For Spring’s entry-level market near Old Town Spring and the older FM 1960 corridor, FHA financing is actively used, and assistance programs can make a real difference on cash to close. For Springwoods Village or Augusta Pines buyers in the $400,000 to $550,000 range, conventional financing with a standard conforming loan or a HomeReady option is usually the strongest fit for borrowers with solid credit. VA-eligible buyers anywhere in Spring should run a VA scenario first, because the zero-down structure and absence of monthly mortgage insurance often produce the most favorable monthly payment at an equivalent purchase price. You can compare programs in more detail in the Houston, TX home loans guide.

How Do MUD Taxes Affect Your Spring, TX Mortgage Payment?

MUD stands for Municipal Utility District. It is one of the most important and most often misunderstood parts of buying a home in the Spring area. If you are moving from another state or from inside the loop, MUD taxes may be a brand new concept.

Many of Spring’s master-planned and newer subdivisions were built on land that needed new infrastructure: water lines, sewer systems, drainage, and roads. Rather than asking developers to absorb that cost entirely, Texas law allows the creation of MUD districts, which are separate taxing entities that fund and maintain the infrastructure. Once the bonds are paid down, which can take many years, MUD rates typically decrease or fold into the county tax base.

For Spring buyers, MUD taxes layer on top of county and school district taxes. In some communities, the combined MUD levy adds 0.4% to 0.9% to your effective tax rate. On a $360,000 home, that could mean an additional $1,440 to $3,240 per year, or roughly $120 to $270 per month added to your escrow payment. These are illustrative figures based on typical MUD ranges; actual amounts vary by district and are subject to annual adjustment.

Here is what to do during the option period to confirm your MUD costs:

1. Request the MUD certificate. Your title company orders a MUD certificate as part of closing, but you want to see it during the option period, not after you have committed. The certificate shows the current MUD rate, any outstanding bonds, and any special assessments.
2. Calculate the full effective tax rate. Add the MUD levy to the county rate and the school district rate to get the combined effective rate. Apply that to the property’s assessed value, available at HCAD.org for Harris County or MCAD-TX.org for Montgomery County, to estimate your annual tax burden.
3. Factor the homestead exemption. The Texas homestead exemption as of 2026 includes a $140,000 school district exemption plus additional county-level exemptions. You file with the applicable county appraisal district after closing. The exemption reduces your taxable value, which lowers your annual tax. Because the benefit usually starts the following tax year, your first escrow payment may be calculated before it applies.
4. Model the full payment with your lender before you make an offer. A pre-approval letter shows what you can borrow based on purchase price. What it does not show is the payment at the specific address, with that community’s MUD rate, flood insurance if applicable, and any HOA dues. Get that full number before you go under contract.

According to the Harris County Appraisal District, effective tax rates across Spring-area Harris County communities commonly land between roughly 2.2% and 2.9% when MUD levies are included, before exemptions. Montgomery County communities in the northern Spring corridor fall in a similar range. These figures vary by year and are subject to annual appraisal district updates, so verify the rate for any specific property.

How the ExxonMobil Campus Shapes Home Loans in Spring, TX

The ExxonMobil campus on the Spring and Woodlands border, just off I-45, is one of the largest corporate campuses in the country and employs thousands of people. Its presence is a major reason the Springwoods Village and CityPlace developments grew so quickly, and it brings a steady stream of relocation buyers to the Spring market each year.

Relocation buyers tend to share a few traits that shape how their financing comes together. Many arrive with strong credit profiles and corporate relocation packages that may include closing cost assistance or temporary housing. For these buyers, conventional and jumbo financing are usually the dominant programs, depending on the purchase price and the village.

If you are relocating for a role at the campus, a few items are worth coordinating early. First, confirm how your relocation package treats any lender-paid or employer-paid closing costs, since that affects how the loan is structured. Next, line up your pre-approval before you start touring, because Spring’s newer inventory near the Grand Parkway moves quickly. Finally, ask your lender to model the full payment, including MUD and county taxes, so the offer you write reflects the true monthly cost, not just principal and interest.

Is Down Payment Assistance Available for Home Buyers in Spring, TX?

Yes, and several programs match the Spring buyer profile well. Because Klein ISD and Spring ISD teachers, healthcare workers, and first responders make up a meaningful share of the local buyer pool, the Texas State Affordable Housing Corporation (TSAHC) programs are frequently relevant for home loans in Spring, TX.

TSAHC: Homes for Texas Heroes

Teachers, firefighters, EMS, police, correctional officers, and veterans may qualify for a grant of up to 5% of the loan amount that never needs to be repaid, or a forgivable deferred second lien forgiven after a set period. For a Klein ISD or Spring ISD teacher buying in the $280,000 to $400,000 range, this program can cover the down payment on a conventional loan and a portion of closing costs, subject to income limits and program availability. The program works with both FHA and conventional financing.

TSAHC: Home Sweet Texas Home

For Spring buyers who do not work in a qualifying occupation, Home Sweet Texas Home offers the same up-to-5% assistance to any Texas buyer who meets income limits. Income limits in the Spring area vary by county and household size. The assistance is structured as a grant or a forgivable deferred loan. Program income limits and availability are subject to change and must be confirmed at the time of application.

TDHCA: My First Texas Home and My Choice Texas Home

The Texas Department of Housing and Community Affairs runs two statewide programs relevant to Spring buyers. My First Texas Home pairs a 30-year fixed-rate first mortgage at a below-market rate with up to 5% in down payment and closing cost help for first-time buyers and veterans. My Choice Texas Home is the same in structure but open to repeat buyers as well, which widens the pool of eligible Spring purchasers. According to the Texas Department of Housing and Community Affairs, program rates and funding availability change throughout the year, so confirming eligibility before going under contract is essential.

County-Level Programs

Harris County HFC programs may be available for buyers purchasing in the Harris County portion of Spring, which covers much of the central and eastern community. Buyers in the Montgomery County sections to the north follow Montgomery County and statewide rules instead. Because Spring straddles the county line, the program that applies depends entirely on the property address, not the Spring mailing address.

Home Loans in Spring, TX: Five Things to Verify Before You Go Under Contract

Spring’s two-county structure means a few extra homework items pay off before you lock in a purchase price and a loan amount. Run through this list while you still have the option period to act on what you find.

1. Confirm the property county. Harris or Montgomery. This drives assistance eligibility, the applicable appraisal district, and your tax math. Do not assume based on the Spring mailing address.
2. Get the MUD certificate during the option period. Request it early, not at the closing table. Understand the current MUD rate and whether the bonds are paid down or still accruing, then ask your lender to fold the MUD levy into your full payment estimate.
3. Check the flood zone at the specific address. Spring sits in the Cypress Creek and Spring Creek watersheds, so flood determination matters. Ask your lender to run the flood determination on the property. If the home is in a Special Flood Hazard Area, the lender will require flood insurance, and that premium is added to your monthly payment.
4. Ask which assistance programs apply to your county and job. If you teach in Klein ISD or Spring ISD, or work in a first-responder or healthcare role, Homes for Texas Heroes may help with your down payment on a qualifying purchase. That conversation should happen before you are under contract.
5. Model the full payment, not just principal and interest. In Spring, property tax plus MUD tax plus any HOA dues plus insurance can add several hundred dollars a month to the base payment on a mid-range home. Knowing that full number before you shop prevents the most common Spring mortgage surprise: qualifying for a price that produces a payment you did not plan for once every cost is included.
